Service data transmission method, network equipment and terminal equipment

Technical Field

The embodiment of the application relates to the field of communication, and in particular relates to a method for transmitting service data, network equipment and terminal equipment.

Background

In a wireless communication system, video services occupy more and more network resources, especially live video services. How to guarantee the experience of video service users is an urgent problem to be solved by a wireless network. From the mode of live broadcast services, live broadcast services can be divided into three main categories: the stream pushing process and the playing process are both used for data transmission through a wireless network; only the playing process carries out data transmission through a wireless network; only the push flow process performs data transmission over the wireless network.

When service data is transmitted through a wireless network, the network side cannot configure network resources according to the requirements of video users, so that the experience of the video users is affected.

Disclosure of Invention

The embodiment of the application provides a method for transmitting service data, network equipment and terminal equipment, which can reasonably configure network resources and improve user experience.

In a first aspect, a method for service data transmission is provided, including: the network equipment acquires the characteristic information of the service data; the network equipment determines scheduling information for transmitting the service data according to the characteristic information; and the network equipment transmits the service data with the terminal equipment according to the scheduling information.

The network equipment acquires the characteristic information of the service data, determines the scheduling information for transmitting the service data according to the characteristic information, and transmits the service data with the terminal equipment according to the scheduling information, so that the network equipment can distribute the scheduling information according to the requirements of different service data, thereby reasonably utilizing network resources and improving user experience.

In some possible implementations, the service data is video service data, and the characteristic information includes at least one of buffering capability information, data frame transmission interval information, service data request period information, and mobility information.

If the service data is video service data, the feature information acquired by the network device may be at least one of cache capability information, data frame transmission interval information, service data request period information, and mobility information, and the network device may further determine scheduling information for transmitting the service data according to the feature information. Therefore, the network equipment can more accurately determine the scheduling information according to the requirement of the service data, thereby further reducing the influence on the user experience.

In some possible implementation manners, the feature information may also be type information of the service data, which is used to distinguish the type of the service data, that is, the service data is service data to be uploaded in a stream pushing process or service data to be downloaded in a playing process, and the network device can distinguish different types of service data according to the service type information of the service data and allocate appropriate scheduling information to the service data, so that network resources can be reasonably utilized.

In some possible implementations, the transmitting, by the network device and the terminal device, the service data according to the scheduling information includes: the network equipment sends the scheduling information to the terminal equipment; the network device receives the service data, and the service data is sent by the terminal device according to the scheduling information.

In the flow pushing process, the network equipment sends the determined scheduling information to the terminal equipment, and the terminal equipment uploads the service data to the network equipment according to the scheduling information and the like, so that the smooth data uploading in the flow pushing process is ensured.

In some possible implementations, the transmitting, by the network device and the terminal device, the service data according to the scheduling information includes: and the network equipment sends the service data to the terminal equipment according to the scheduling information.

The process corresponds to a playing process, and the network equipment sends the service data to the terminal equipment according to the determined scheduling information, so that network resources can be reasonably utilized, and the influence of the playing process on user experience is reduced.

In some possible implementation manners, in the stream pushing process, after the network device sends a service data packet to the terminal device according to the scheduling information, the terminal device may also return feedback information to the network device for the service data packet, where the feedback information may also affect transmission delay of a data packet to be sent next. Therefore, when the network device determines the scheduling information of the service data next time, the network device can determine more appropriate scheduling information according to the scheduling information and the feedback information, so that the network device can configure the scheduling information more reasonably, and user experience is improved.

In some possible implementations, the method further includes: the network equipment acquires the data volume of the service data; wherein, the determining, by the network device according to the feature information, scheduling information for transmitting the service data includes: the network device determines the scheduling information according to the characteristic information and the data volume.

In the process of stream pushing, when there is service data transmission, the network device may obtain the data volume of the service data that the UE needs to transmit, and determine the scheduling information for transmitting the service data according to the data volume and the feature information. Therefore, the network equipment can more accurately determine the scheduling information of the service data, thereby better ensuring the experience of the user.

In some possible implementations, the acquiring, by the network device, the characteristic information of the service data includes: and the network equipment receives the characteristic information sent by the terminal equipment.

In the process of stream pushing, the network device obtains the characteristic information of the service data, and can obtain the characteristic information in a manner reported by the UE before the service data is to be transmitted. In the playing process, the network device may send the characteristic information of the first data packet received by the terminal device to the network device, so that the network device may physically distribute the scheduling information for the next data packet according to the characteristic information.

In some possible implementations, the acquiring, by the network device, the characteristic information of the service data includes: the network device obtains the feature information from a server.

In the process of acquiring the service characteristics, the server may acquire the characteristic information of the service data sent by the terminal device, and send the characteristic information to the network device after the server acquires the characteristic information.

The data amount of the service data acquired by the network device may be determined by acquiring refresh rate information, encoding compression rate information, video resolution information, and the like of the service data. For example, the size of the video service data is video resolution refresh rate compression rate pixel size. Therefore, the network equipment can more accurately determine the scheduling information of the service data, thereby better ensuring the experience of the user.

In some possible implementations, the service data is video service data; wherein, the acquiring, by the network device, the data volume of the service data includes: the network equipment acquires code rate information and playing duration information of video service data; and the network equipment determines the data volume of the video service data according to the code rate information and the playing time length information of the video service data.

The data size of the service data acquired by the network device may be determined by acquiring code rate information and video playing duration information of the service data. For example, the size of the video service data is bitrate playing duration. Therefore, the network equipment can more accurately determine the scheduling information of the service data, thereby better ensuring the experience of the user.

In some possible implementations, the acquiring, by the network device, the data volume of the service data includes: the network equipment receives the data volume of the service data sent by the terminal equipment when the data volume in the cache changes; or the network device receives the data volume of the service data sent by the terminal device when the scheduling grant value in the last scheduling information is smaller than the data volume in the buffer.

The terminal device may report the data volume of the service data when the buffer changes, for example, when the data in the buffer increases or the data in the buffer decreases, the data volume of the current service data is reported to the network device, where the data volume may be represented by the buffer size and may be reported by a packet header of the user plane. When the terminal device uploads a plurality of data packets, the network device allocates the scheduling information to the terminal device, but the scheduling authorization value in the scheduling information cannot be matched with the data amount in the terminal device buffer, for example, the scheduling authorization value is much smaller than the data amount in the buffer, and at this time, the terminal device can report the data amount of the current service data, so that the network device can allocate appropriate scheduling information (i.e., the scheduling authorization value) according to the data amount and the characteristic information, thereby being capable of satisfying the smooth transmission of the subsequent service data.

In some possible implementations, the scheduling information includes at least one of resource configuration information, scheduling priority information, multi-stream or multi-system configuration information.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The method is mainly applied to a mobile communication system, and the system architecture comprises terminal equipment and network equipment. A terminal device can also be called an access terminal, subscriber unit, subscriber station, mobile, remote station, remote terminal, mobile device, User terminal, wireless communication device, User agent, User device, or User Equipment (UE). The access terminal may be a cellular phone, a cordless phone, a SIP (Session Initiation Protocol) phone, a WLL (Wireless Local Loop) station, a PDA (Personal Digital Assistant), a handheld device with Wireless communication function, a computing device or other processing device connected to a Wireless modem, a vehicle mounted device, a wearable device, and a terminal device in a future 5G network.

The network device may be a Base Transceiver Station (BTS) in Global System for Mobile communications (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB, NB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB, or eNodeB) in Long Term Evolution (Long Term Evolution, LTE), or a relay Station or an Access point, or a vehicle-mounted device, a wearable device, and a network device in a future 5G network.

Or the network device may also be any relay device in the process of transmitting the service data, and the relay device may also be a user equipment. The network device may also be divided into two logical functional entities, such as a control plane and a user plane, which are not limited in this application.

Fig. 1 shows an application scenario of an embodiment of the present application. As shown in fig. 1, a host continuously transmits live content to a live server through a push streaming process, where the host is a service source provider, typically a terminal. The audience acquires the live content through the playing process, and acquires the content information provided by the main broadcast in real time, wherein the number of the audience may change in real time, and is generally a plurality of terminals.

The user experience is an important criterion for evaluating video services, and in the video live broadcast process, the push streaming process and the playing process both affect the experience of audiences.

In the current mobile communication system, the network side generally sends the video service data and other service data together in one bearer, and when scheduling data, the video service data cannot be distinguished, even if the network side puts the video service in one bearer alone, the network side is difficult to accurately obtain the requirements of the video service user, and is difficult to process the data packet of the video user according to the requirements, so that the experience of the video user is affected.

The communication system of the application scenario of the present application has been described in detail above with reference to fig. 1, and the following describes a method and an apparatus for transmitting service data that can be applied to the system in detail.

One embodiment of the present application is described in detail below in conjunction with fig. 2. It should be noted that this is only for helping the skilled person to better understand the embodiments of the present application, and does not limit the scope of the embodiments of the present application.

In an embodiment of the present application, a network device obtains feature information of service data, and determines scheduling information for transmitting the service data according to the feature information, so that the network device can perform transmission of the service data with a terminal device according to the scheduling information. Therefore, the embodiment of the application can distinguish different service data according to the characteristic information of the service data, namely, different scheduling information is allocated according to different service data, so that network resources can be reasonably utilized, and the user experience of high-priority service data is improved.

In the embodiments of the present application, the service data to which the solution is directed is service data of a video service, and the solution is also applicable to other non-video services, and the present application is not limited thereto. The Video service can be further divided into a live Video and a non-live Video (VOD), wherein the optimization for the playing process can also be applied to the VOD service.

Fig. 2 is an interaction flowchart of a method for transmitting service data according to an embodiment of the present application.

201. The network equipment acquires the characteristic information of the service data.

The service data may be a service data stream composed of a plurality of service data packets, where the obtained feature information may be feature information for a first service data packet or any one service data packet in one service, that is, the feature information may be applied to each data packet of one service; or the feature information may be feature information of each service data packet in a plurality of data packets of one service, that is, the feature information of each data packet of one service is obtained, where the data packet may be a data packet of an application layer or a data packet of a link layer, which is not limited in this embodiment of the present application. Alternatively, the characteristic information of each data packet may be obtained directly from other devices on the network side, or indirectly, for example, the network device obtains the characteristic information through statistics or calculation by using the obtained other information.

If the service data is video service data, the feature information of the service data includes at least one of service type information, cache capability information, data frame transmission interval information, service data request period information, and mobility information. The caching capability is used for indicating whether the service data is allowed to be cached at the receiving end. Specifically, the receiving end may be any routing node, for example: the network side device, the service server, or the user equipment of the viewer receiving the stream information. According to the buffering capacity, the network side can decide whether certain data packets or data frames can be discarded during transmission. For example: if the service data allows the cache of the receiving end, the network side can not discard the data packet; if the service data does not allow the buffer of the receiving end, the network side can discard the data packet according to the network condition and the like. Optionally, whether caching at the receiving end is allowed or not is determined by the application layer or the service. For example: when a Hypertext transfer protocol (HTTP) request carries cache capability information, and when a parameter therein is set to be no-cache or no-store, caching is not allowed.

The characteristic information of the traffic data may include transmission bandwidth requirement information to indicate a requirement of the traffic data transmission for a network side resource, and specifically, the transmission bandwidth requirement information may be at least one parameter of throughput rate information, code rate information and frame rate information (expressed as refresh rate information) required for transmission. Taking a live video as an example, in the stream pushing process, when the transmission bandwidth information is used to indicate that the service data is uploaded, the requirement on the air interface resource or the requirement on the throughput rate of the transmission layer is met. In the playing process, the transmission bandwidth information is used for indicating the speed guarantee when the service data is downloaded to the network side. Further, the transmission bandwidth requirement may also contain key frame transmission interval information (denoted as data frame transmission interval information). Wherein, the key frame is the complete reservation of a frame of picture; generally, only key frame data is needed to obtain a picture when decoding, and decoding of non-key frames depends on key frames.

The characteristic information of the service data may include a data request mode, specifically, a periodic request and an aperiodic request. Further, in the periodic request mode, the data request mode further includes requested period information. For example: in the playing process of the VOD or live video, the terminal device determines whether to initiate a download request of the next video segment according to the video playing condition, so that the request of the video segment is usually periodic, and the period is the playing duration of one or more segments. Further, the data request mode may be a buffer size and/or a buffer threshold value of the ue for the service; from this information, the network can obtain a data request pattern. For example: when the cache threshold value is satisfied, the user equipment at the receiving end initiates a service request, and the network side equipment obtains the periodic request and the request period of the user equipment according to the information.

The mobility information of the service data is used for indicating the type of the service, mainly aiming at the live video service, and used for distinguishing whether a service data provider is mobile or not in the process of pushing flow.

Optionally, the feature information of the service data may further include identification information of the service data and/or type information of the service data.

The identification information of the service data may be used to identify the service data corresponding to the type information. Specifically, the identification information of the service data may be an Internet Protocol (IP) address or port information of the service data stream, or may also be other information of an IP quintuple, or may also be an identification of the service data stream, and the like, which is not limited in this embodiment of the application.

The type information of the service data is used for distinguishing the type of the service data, and specifically can be video service, web browsing, games and the like; or a video live broadcast service indication; or is an indication of a plug flow process; or a video live play process indication. The type information of the service data can also be used for distinguishing different live broadcast types, which mainly comprise entertainment live broadcast and communication live broadcast. For example, live entertainment mainly includes live television, live broadcasting in live broadcasting rooms, live outdoor broadcasting, and the like; the communication live broadcast mainly comprises video call and the like. The type information is only an example, and the video services may also be classified according to the characteristics of the service data, where the type information may be short delay service or long delay service. The long delay and the short delay are distinguished according to the specification of the network side. Optionally, in an embodiment of the present application, the acquiring, by the network device, the characteristic information of the service data includes: and the network equipment receives the characteristic information sent by the terminal equipment. For example, the UE reports the feature information through a Control plane signaling, and specifically, the UE may send the feature information of the service data to the network device through a Radio Resource Control (RRC) signaling; or the UE reports the feature information of the service data through the user plane data channel, for example, the feature information is carried in a packet header of the data packet, and the like.

Optionally, the network device may obtain the list corresponding to the identification information and the type information of the service data in advance. Thus, the network device can acquire only any one of the identification information or the type information of the service data, and can acquire the other information through the list. Since the list does not need to be acquired each time, network resources are saved. For example, the network device only obtains the identification information of the service data, and can obtain the service data type corresponding to the service data through the list.

Optionally, in an embodiment of the present application, the acquiring, by the network device, the characteristic information of the service data includes: the network equipment receives the characteristic information sent by the server.

Specifically, the server sends the service characteristic information to the network side device through an Rx interface; or the server carries the service characteristic information in the packet header of the service data packet and sends the service characteristic information to the network equipment; or the server sends the service characteristic information to the network side equipment in an application program interface mode.

Optionally, the server may obtain the feature information sent by the terminal device, and then send the obtained service feature information to the network side device. The server may send feature information, for example, feature information indicating traffic data in a transport layer packet header of a data packet, to the network device through a data channel of the user plane. It should be noted that the service feature information sent by the server to the network side device may be part of the feature information acquired from the terminal device, and may also include feature information of service data owned by the server itself.

Optionally, the network side may obtain part of the feature information from the server and the terminal device, respectively, to obtain all the required feature information.

According to different functions of the feature information, the feature information may be transmitted to the network side in the same manner or in different manners. For example: the caching capacity can be sent to the network side equipment in the beginning stage of the live video in an RRC signaling mode, the transmission bandwidth requirement is sent to the network side equipment by the server through an Rx interface in the data transmission process, and the changed parameters can be sent to the network equipment according to the change of the transmission bandwidth requirement. For example: in the process of video playing or downloading, the user equipment may send the transmission bandwidth requirement to the network side equipment through an RRC signaling or a Transmission Control Protocol (TCP) packet header when requesting to download the fragments, where each fragment requires reporting of a transmission bandwidth requirement parameter once, and the service identifier only needs to be reported to the network side equipment at the service start stage.

It should be noted that, for the live video service, the network device serving in the stream pushing process and the network device serving in the playing process may be the same or different, and this is not limited in this application.

It should be understood that the server may be a service providing server, for example, a video content provider or a local cache server, which is not limited in this application.

Optionally, the network device may further obtain a streaming media protocol and/or a mode of a transport layer of the video service.

Specifically, the network device may implement transmission of the service data according to the acquired streaming media protocol and/or a mode of a transport layer, and the like. Specifically, the media processing modes supported by the application layer include: a Real Time Messaging Protocol (PTMP), a Dynamic rate adaptation technology (HTTP live Streaming, HLS), a Dynamic Adaptive Streaming over HTTP (DASH), a Progressive Download over HTTP (HPD), and an Adaptive Streaming over HTTP (HAS), which are not limited in the embodiments of the present application. The modes of the transport layer are: user Datagram Protocol (UDP), TCP, Real-time Transport Protocol (RTP), and the like, which are not limited in this embodiment.

202. And the network equipment determines scheduling information for transmitting the service data according to the characteristic information of the service data.

Optionally, the network device may preset scheduling information corresponding to different service data, so that the scheduling information may be determined according to the characteristic information of the service data. Specifically, the network device may identify the service data as the push flow service data according to the type information of the service data, and determine the scheduling information preset for the service data according to the identification information of the service data.

It should be understood that the network device determines the scheduling information according to the characteristic information of the service data, and may determine the scheduling information only once when starting transmission, and the data packet of the whole service data is sent according to the scheduling information; or the network device may determine once for each service data packet in the transmission process, which is not limited in this embodiment of the present application.

Optionally, in an embodiment of the present application, the scheduling information includes at least one of resource configuration information, scheduling priority information, multi-stream or multi-system configuration information.

Specifically, the network device may determine resources occupied by transmitting the service data, priority information of scheduling, multi-stream or multi-system configuration information, and the like, thereby ensuring smooth progress of the stream pushing process. The multiflow or multisystem configuration information refers to configuration information for transmitting service data through different channels or configuration information for transmitting service data in different systems. The priority between different traffic data streams may be preset, e.g. video traffic data has a higher priority than audio data. The push stream service of the video service data has higher priority than the play service or the interactive service. Optionally, the scheduling priority of the service data may also set a time limit, for example, the time limit is set to 100ms, and after 100ms of the priority is determined, the priority needs to be determined again.

It should be understood that the scheduling information may also include a data amount of the service data that can be uploaded by the terminal device within a period of time, a transmission mode parameter for the terminal device to transmit the service data, admission information of the service data, service data multi-stream transmission information and/or access/system information of the terminal device, configuration information of static or semi-static scheduling or continuous scheduling, and the like, which is not limited in this application.

Optionally, the network device may further determine scheduling information for transmitting the service data according to at least one of the service type information, the buffering capability information, the data frame transmission interval information, the service data request period information, and the mobility information. The scheduling information may be any information related to a scheduling policy, which is not limited in this application.

The caching capability information refers to whether the service data supports caching in the network equipment. The network device may decide whether to save the transmitted service data (i.e., data packets or data frames) during the transmission process according to the buffering capability information. If the business data caching is supported, the business data is stored; otherwise, it is discarded.

It should be understood that the service server, or the user equipment receiving the service data, may also determine whether to store the service data according to the caching capability information.

The transmission bandwidth requirement information is used to indicate a requirement for an air interface resource when a service data stream is uploaded, and a specific form may be at least one parameter of throughput rate information, code rate information, and frame rate information (denoted as refresh rate information) required for transmission. The frame rate information refers to the number of frames per second of a refreshed picture, and can also be understood as how many times per second the graphics processor can refresh. For movie content, the frame rate refers to the number of fine frames displayed per second. The network device may determine the scheduling information according to the bandwidth requirement of the service data. That is, if the bandwidth required by the service data is large, more network resources are allocated to the service data; if the bandwidth required by the service data is smaller, less network resources are allocated to the service data. Therefore, the network equipment can more reasonably distribute the network resources and improve the utilization rate of the network resources.

For example, after the network device identifies the type of the service data stream according to the identification information and the type information of the service data stream, the network device determines resource configuration information, scheduling priority and the like that need to be occupied during service data transmission according to the code rate information of the UE, and then the network device allocates corresponding network resources, thereby ensuring smooth progress of the stream pushing process.

The key frame is the complete reservation of a frame of picture, the picture can be obtained only by key frame data when decoding, and the decoding of non-key frames depends on the key frame. The network device can determine the network resources allocated to the service data according to the transmission interval of the key frame, so that the network resources can be allocated more reasonably, and the utilization rate of the network resources is improved.

Optionally, in an embodiment of the present application, the feature information may further include a data request mode, where the data request mode is a periodic request mode or an aperiodic request mode.

Specifically, for the playing process of the video service data, the characteristic information may further include a data request mode. The data request mode may be specifically a periodic request mode or an aperiodic request mode. The periodic request mode also comprises requested period information.

For example, as shown in fig. 3, for a video stream including a plurality of data packets, the terminal device may continuously request the plurality of data packets, so that the number of service data packets in the buffer or the playing time meets a certain requirement, for example, is higher than a preset threshold. After that, the terminal device may request and download the service data packet periodically, which is taken as T. In one T, ON represents the downloading process of the service data, OFF represents no data downloading, and the steps are repeated in sequence until all the downloading of the service data stream is completed. The T of each period is basically the same, but the ON duration may be different, for example, the size of the service data requested by the terminal device and whether the service data transmission process is smooth or not may affect the duration of the downloading process.

Optionally, in an embodiment of the present application, the method further includes: the network equipment acquires the data volume of the service data; wherein, the determining, by the network device according to the feature information, scheduling information for transmitting the service data includes: and the network equipment determines scheduling information for transmitting the service data according to the characteristic information and the data volume.

Specifically, in an embodiment of the present application, the network device may further obtain a data amount of service data that needs to be transmitted by the UE, and determine scheduling information for transmitting the service data according to the data amount and the feature information. Thus, the network device may determine the scheduling priority information and the resource configuration information of the service data more accurately, or the network side may determine the scheduling mode for the service more accurately, for example: and configuring a continuous scheduling mode or a semi-static scheduling mode for the service, thereby better ensuring the experience of the user. The continuous scheduling mode or the semi-static scheduling mode refers to that the UE can continuously transmit data for a period of time based on the scheduling grant of the network side, and at the continuous transmission stage, the network side does not need to transmit the scheduling grant for each uplink data packet. Specifically, the duration of continuous transmission may be based on the configuration of the network side.

Alternatively, the data amount of the service data acquired by the network device may be determined by acquiring refresh rate information, encoding compression rate information, video resolution information, and the like of the service data. Or the data size of the service data acquired by the network device may be determined by acquiring the code rate information and the video playing time length information of the service data.

For example, the size of the video service data is video resolution refresh rate compression rate pixel size; or the size of the video service data is code rate and playing duration; here, the compression rate information may be an encoding mode.

It should be understood that, the terminal device reports refresh rate information, coding compression rate information, and video resolution information of the video service data, or reports bit rate information and video playing duration information of the video service data, so that the network device can calculate the data volume of the video service data, and the reporting process can be performed only once in a service data uploading process until all the services are uploaded.

Optionally, the terminal device may directly report a Data volume of service Data to be transmitted, where the Data volume of the service Data may be a Data volume buffered by an application layer, a Data volume buffered by a transport layer, or a Data volume of Radio Link Control (RLC)/Packet Data Convergence Protocol (PDCP), and the like, and the embodiment of the present application does not limit this.

Optionally, if the data volume of the service data is the data volume of the RLC/PDCP, in order that the network device can relatively grasp the data volume of the service data to be transmitted in real time, the UE may report the data volume in the buffer in real time, for example, the data volume of the service data is indicated in real time in the process of sending the service data.

It should be understood that the data volume of the service data sent by the terminal device may be a direct sending data volume value, or may be sending indication information, and the network device knows the data volume of the service data according to the indication information.

Optionally, the UE may report the data volume of the service data when the buffer changes, for example, when the data in the buffer increases or the data in the buffer decreases, the data volume of the current service data is reported to the network device, where the data volume may be represented by the buffer size and may be reported by a packet header of the user plane. The invention is not limited in this regard.

It should be understood that the data amount in the RLC/PDCP buffer may be full all the time during the transmission of the traffic data, that is, the data amount is a fixed value, and the data in the buffer is not gradually decreased until the end of the data transmission process.

Optionally, the network device receives the data volume of the service data sent by the terminal device when the scheduling grant value in the last scheduling information is smaller than the data volume in the buffer.

When the terminal device uploads a plurality of data packets, the network device allocates the scheduling information to the terminal device, but the scheduling authorization value in the scheduling information cannot be matched with the data amount in the terminal device buffer, for example, the scheduling authorization value is much smaller than the data amount in the buffer, at this time, the terminal device can report the data amount of the current service data, so that the network device can allocate appropriate scheduling information (including an appropriate scheduling authorization value) according to the data amount and the characteristic information, thereby being capable of satisfying the smooth proceeding of the subsequent service data transmission.

203. And the network equipment transmits the service data with the terminal equipment according to the scheduling information.

Optionally, the network device, according to the scheduling information, transmitting the service data with the terminal device includes: the network equipment sends the scheduling information to the terminal equipment; the network device receives the service data, and the service data is sent by the terminal device according to the scheduling information.

Specifically, the process corresponds to a stream pushing process, the network device sends the determined scheduling information to the terminal device, and the terminal device uploads the service data to the network device according to the resource configuration information, the scheduling priority information and the like, so that the network resource can be reasonably utilized.

It should be noted that, if the network side device is an access network device, it may optionally need to be determined according to a policy of the core network node and a service quality parameter when determining the scheduling information of the transmission data in step 202.

Optionally, as shown in fig. 4, in the push flow process, when the terminal device uploads the service data to the network device, the data packet may also be periodically uploaded. For example, the terminal device may upload multiple data packets in advance, and then periodically upload the multiple data packets, so as to ensure that the service data can be kept continuous. Within a T, ON indicates a process of service data upload, and OFF indicates no data upload.

Optionally, in an embodiment of the present application, in the stream pushing process, after the terminal device sends a service data packet to the network device according to the scheduling information, the terminal device may further receive feedback information and the like returned by the network device for the service data packet, where the feedback information may also affect transmission delay of a data packet to be sent next, and therefore, the terminal device may select a more appropriate manner to send the remaining service data packet according to the scheduling information and the feedback information.

It should be noted that the feedback information may be control information, such as synchronization information or control information of an application layer; or the feedback information may also be indication information indicating whether the service data is correctly transmitted, which is not limited in this application.

Optionally, the network device, according to the scheduling information, performing, by the network device, transmission of the service data with the terminal device includes: and the network equipment sends the service data to the terminal equipment according to the scheduling information.

Specifically, the process corresponds to a playing process, and the network device sends the service data to the terminal device according to the determined scheduling information, so that network resources can be reasonably utilized.

For example, the service data is video service data, and the network device can reasonably distribute the service data to the video service data in the playing process, so that the user experience can be improved.

Optionally, in an embodiment of the present application, in the playing process, after the network device sends a service data packet to the terminal device according to the scheduling information, the terminal device may further return feedback information to the network device for the service data packet, where the feedback information may also affect transmission delay of a data packet to be sent next. Therefore, when the network device determines the scheduling information of the service data next time, the network device can determine more appropriate scheduling information according to the scheduling information and the feedback information, so that the network device can configure the scheduling information more reasonably, and user experience is improved.

Therefore, in the method for transmitting service data according to the embodiment of the present application, the network device obtains the feature information of the service data, determines the scheduling information for transmitting the service data according to the feature information of the service data, and transmits the service data with the terminal device according to the scheduling information, so that the network device can allocate the scheduling information according to the requirements of different service data, thereby reasonably utilizing network resources and improving user experience.
